GAS ABSORBING ATTACHMENT Filed May 14, 1956 United States Patent GAS ABSORBING ATTACHMENT Cayetano Aguas, Pasadena, Calif.

Application May 14, 1956, Serial No. 584,620

2 Claims. (Cl. 261-16) This invention relates to a gas absorbing attachment, particularly for internal combustion engines and vehicles, in which certain noxious gases are exhausted by the engine during its operation.

An object of my invention is to provide a novel gas absorbing attachment in which the exhaust gases from an engine are required to pass into a container and to pass through a water spray, so that certain components of the gas are thus absorbed in the water.

Another object of my invention is to provide a novel gas absorbing attachment of the character stated, in which the water bath Within the attachment is agitated so that the entire transverse area of the attachment is filled with a water vapor or water drops, so that the exhaust gas will be more effectively absorbed.

Still another object is to provide a novel gas absorbing attachment of the character stated, which is simple in construction, inexpensive to manufacture, and effective in operation.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

In the drawing:

Figure 1 is a front elevation of my gas absorbing attachment with parts broken away to show interior construction.

Figure 2 is a top plan view of my gas absorbing attachment with the protective cap removed.

Figure 3 is a top plan view of my gas absorbing attachment.

Referring more particularly to the drawing, the numeral 1 indicates a cylindrical housing which is open at its forward end, as shown at 2, and the rear end is closed by the wall 3. A wall 4 partly closes the front end 2 of the housing and this wall is so arranged that the upper half of the housing is open for the ingress of gases, as will be further described. The wall 4 acts as a dam or a retainer so that a quantity of water 5 will be retained within the housing 1 at all times. This quantity of water substantially fills the lower half of the housing 1 and acts as a bath to absorb and retain certain elements of the exhaust gases, as well as any heavy particles contained therein. Water is continuously and very slowly fed into the housing 1 to maintain the bath 5 by means of the pipe 6, which extends into the housing 1 adjacent the forward end thereof and back of the wall 4. The portion of the pipe 6 within the housing 1 has several very small holes drilled therein so that water drops slowly out of the pipe and into the housing back of the wall 4. A suitable valve 7 in the pipe 6 controls the flow of water into the housing 1. The exhaust pipe 8 is directed into the open end of the housing 1 and preferably above the upper edge of the wall 4, so that the exhaust gases are directed longitudinally into the housing 1. The exhaust gases pass into the housing 1 over the water bath 5 and since the rear of the housing 1 is closed by the wall 3 the exhaust gases must be expelled at the forward or open end of the housing 1 and are Patented May 5, 1959 retarded somewhat by the flow of incoming exhaust gases by the pipe 8. It will thus be evident that there is great turbulence within the housing 1, and the exhaust gases are thus forced into the water bath 5 before they pass out counter to the incoming flow of exhaust gas. The exhaust pipe 8 is spaced from the open end of the housing 1 so that the jet action of the exhaust gases will draw outside air into the housing along with the exhaust gases. Thus a greater turbulence is created within the housing 1 and also a better intermingling of the exhaust gases, the outside air and the water.

A plurality of beater blades 9 are mounted on a transverse shaft 10 which is journaled in the wall of the housing 1. The shaft 10 is freely rotatable and the incoming gases will strike the blades 9, thus causing the shaft 10 and the blades to rotate for the purpose of agitating the water bath 5. The blades 9 dip into the water bath 5 as they rotate, thus effectively agitating the water and causing a spray through which the incoming exhaust gases must pass. This provides again an effective means of providing a spray or droplets of water through which the exhaust gases and outside air must pass while bath entering and leaving the housing 1, and thus more efiectively absorbing the gases. It is evident that due to the spraying and agitation of the water within the housing 1 that quantities of this water will be carried out of the housing with the exhaust gas, thus requiring a constant replacement of the water which is accomplished by the intake water pipe 6. A slot 11 is provided in the housing 1 at the forward end thereof and this slot is provided only for assembly purposes. After the pipe 6 and the beater blades 9 have been assembled it is necessary to cover the slot 11, and this is accomplished by the cap 12 which fits over the slot 11 and preferably is held in position by a close fit or, if necessary, a set screw can be inserted through the cap.

Having described my invention, I claim:
